REST API 面试题与答案

问题 36. What distinguishes monolithic, SOA, and microservices architectures from one another?

• With a monolithic architecture, all the software parts of a program are put together and neatly wrapped in one large container.
• A group of services that communicate with one another is referred to as a service-oriented architecture. Simple data exchange or the coordination of an action between two or even more services are both possible forms of communication.
• Microservices Architecture is a type of architectural design that organizes an application as a group of tiny, independent services based on a business domain.

问题 37. Do you think GraphQL is the best choice for creating microservice architecture?

Because GraphQL hides your microservices architecture from the customers, it works perfectly with microservices. From the front end, you want all the data to come from a small API, while from the back end, you want to divide it into microservices. The best technique I'm aware of to do both is by using GraphQL. It enables you to divide the backend into microservices while still giving each application a single API and enabling joins across data from various services.

问题 38. What function does a URI serve in RESTful web services?

Uniform Resource Identifier is what URI stands for. In a REST architecture, a URI identifies each resource. Locating a resource or resources on the server hosting the web service is the purpose of a URI.
